Ownership / SSRM

PI

Shared across the supply chain

Shared control ownership refers to responsibilities and activities related to LLM security that are distributed across multiple stakeholders within the AI supply chain, including the Cloud Service Provider (CSP), Model Provider (MP), Orchestrated Service Provider (OSP), Application Provider (AP), and Customer (AIC). These controls require coordinated actions, communication, and governance across all involved parties to ensure their effectiveness.

Model

Owned by the Model Provider (MP)

The model provider (MP) designs, develops, and implements the control as part of their services or products to mitigate security, privacy, or compliance risks associated with the Large Language Model (LLM). Model Providers are entities that develop, train, and distribute foundational and fine-tuned AI models for various applications. They create the underlying AI capabilities that other actors build upon. Model Providers are responsible for model architecture, training methodologies, performance characteristics, and documentation of capabilities and limitations. They operate at the foundation layer of the AI stack and may provide direct API access to their models. Examples: OpenAI (GPT, DALL-E, Whisper), Anthropic(Claude), Google(Gemini), Meta(Llama), as well as any customized model.

Orchestrated

Owned by the Orchestrated Service Provider (OSP)

The Orchestrated Service Provider (OSP) is responsible for the design, development, implementation, and enforcement of the control to mitigate security, privacy, or compliance risks associated with Large Language Model (LLM)/GenAI technologies in the context of the services or products they develop and offer. The OSP is responsible and accountable for the implementation of the control within its own infrastructure/environment. If the control has downstream implications on the users/customers, the OSP is responsible for enabling the customer and/or upstream partner in the implementation/configuration of the control within their risk management approach. The OSP is accountable for ensuring that its providers upstream (e.g MPs) implement the control as it relates to the service/product the develop and offered by the OSP. This refers to entities that create the technical building blocks and management tools that enable AI implementation. This can include platforms, frameworks, and tools that facilitate the integration, deployment, and management of AI models within enterprise workflows. These providers focus on model orchestration and offer services like API access, automated scaling, prompt management, workflow automation, monitoring, and governance rather than end-user functionality or raw infrastructure. They help businesses implement AI in a structured and efficient manner. Examples: AWS, Azure, GCP, OpenAI, Anthropic, LangChain (for AI workflow orchestration), Anyscale (Ray for distributed AI workloads), Databricks (MLflow), IBM Watson Orchestrate, and developer platforms like Google AI Studio.

Application

Owned by the Application Provider (AP)

The Application Provider (AP) is responsible for the design, development, implementation, and enforcement of the control to mitigate security, privacy, or compliance risks associated with Large Language Model (LLM)/GenAI technologies in the context of the services or products they develop and offer. The AP is responsible and accountable for the implementation of the control within its own infrastructure/environment. If the control has downstream implications on the users/customers, the AP is responsible for enabling the customer and/or upstream partner in the implementation/configuration of the control within their risk management approach. The AP is accountable for carrying out the due diligence on its upstream providers (e.g MPs, Orchestrated Services) to verify that they implement the control as it relates to the service/product develop and offered by the AP. These providers build and offer end-user applications that leverage generative AI models for specific tasks such as content creation, chatbots, code generation, and enterprise automation. These applications are often delivered as software-as-a-service (SaaS) solutions. These providers focus on user interfaces, application logic, domain-specific functionality, and overall user experience rather than underlying model development. Example: OpenAI (GPTs,Assistants), Zapier, CustomGPT, Microsoft Copilot (integrated into Office products), Jasper (AI-driven content generation), Notion AI (AI-enhanced productivity tools), Adobe Firefly (AI-generated media), and AI-powered customer service solutions like Amazon Rufus, as well as any organization that develops its AI-based application internally.

Implementation guidelines

[All Actors]
1. Policy establishment and documentation: 
    a. Identify all external dependencies (third-party libraries, APIs, models, datasets, hosting infrastructure).
    b. Develop formal Supply Chain Risk Management (SCRM) policies that address: Selection and onboarding of third parties, Security posture assessments, Requirements for transparency and attestations.

2. Approval and Governance: 
    a. Define roles and responsibilities for approving and overseeing the SCRM policies.
    b. Involve legal, compliance, and risk functions in formal policy approvals.

3. Communication and Training
    a. Disseminate SCRM policies to relevant internal teams.
    b. Provide role-based training on how to apply policies during procurement, development, integration, and deployment.

4. Application and Enforcement: 
    a. Ensure third-party suppliers are vetted through standardized due diligence (e.g., questionnaires, evidence-based audits).
    b. Apply security clauses and SLAs in contracts.
    c. Integrate enforcement into procurement workflows and automated pipelines (e.g., software composition analysis).

5. Monitoring, Evaluation, and Updating: 
    a. Establish continuous monitoring mechanisms for suppliers (e.g., vulnerability feeds, breach intelligence).
    b. Conduct annual reviews or sooner if there are: Major supplier changes, Regulatory updates, Security incidents.
    c. Maintain version-controlled documentation of policy updates.

Auditing guidelines

1. Ensure GPU sourcing, model deployment layers, and marketplace vendors are covered.

2. Validate sign-offs by risk/compliance leads.

3. Inspect internal SOPs and published transparency reports, to verify communication to internal and external stakeholders.

4. Review onboarding and vetting workflows for open-source, ML libraries, hardware vendors, to specify the implementation depth.     

5. Request sample SBOMs, risk scorecards, or breach history logs, to check the supplier risk evaluation.   

6. Verify the most recent update and trigger events for policy review (e.g., breach, new partner).

7. Check that the policy aligns with recognized cloud security and supply chain risk management standards and applicable regulations.

8. Verify that monitoring metrics or internal/external audits are performed periodically to evaluate policy effectiveness.
